Cover crops can be used to impede soil erosion off of fields.
Posted on April 1, 2015 by Christina Curell, Michigan State University Extension
The reasons why farmers use cover crops are as varied as the number of species that can be used as a cover crop. Traditionally cover crops were used for erosion control. Recent water quality concerns has brought the discussion on cover crops and soil erosion back to the forefront.
Cover crops are a great tool that farmers can use to minimize soil movement off of field. Active roots in the soil hold the soil from water erosion while above ground growth shields soil movement from wind erosion. Covering the soil also protects the soil from rainfall splatter. When it rains, water hits the soil at a great impact causing soil to be displaced. The following chart rates cover crop species ability to decrease soil erosion. The rating encompasses both root and plant growth.
